New vs Old Tax Regime for Home Loan Borrowers After 2026 — Rules, Limits & Worked Examples
Reviewed by CA Nikhil Gupta · Last reviewed 26 September 2026
Corrected 26 September 2026: the earlier version cited Section 72(1) and 72(2) for home loan interest (it is Section 22), and described 80C principal repayment as part of Section 126 (it is Section 123; Section 126 is health insurance).
If you have a home loan, the old vs new regime decision is often made for you — the old regime's home loan deductions (Section 24 interest + Section 80C principal) can save you ₹1–2 lakh or more in tax annually. But this arithmetic changes significantly based on your income level, whether the property is self-occupied or let out, and the loan amount. This guide works through the numbers for home loan borrowers at different income levels under both regimes for Tax Year 2026-27.
Home Loan Tax Deductions — Quick Reference
| Deduction | Section (New Act) | Limit | Old Regime | New Regime |
|---|---|---|---|---|
| Interest on home loan (self-occupied) | Section 22(1)(b) and 22(2) [old: 24(b)] | ₹2 lakh/year | ✅ Available | ❌ Not available |
| Interest on home loan (let-out property) | Section 22(1)(b) [old: 24(b)] | Actual interest (no cap), but HP loss set-off capped at ₹2L | ✅ Available | ✅ Available (deducted from rental income) |
| Principal repayment in EMI | Section 80C (now Section 123) | Within ₹1.5 lakh 80C limit | ✅ Available | ❌ Not available |
| Stamp duty / registration fees | Section 123 [old: 80C] | Within ₹1.5 lakh 80C limit (year of payment) | ✅ One-time, year of payment | ❌ Not available |
| Pre-construction interest (5-year deduction) | Section 22(1)(c) and 22(2) [old: 24(b)] | 1/5th each year for 5 years after possession, within ₹2L limit | ✅ Available | ❌ Not available |
Self-Occupied Property — Old vs New Regime Compared
For a self-occupied home loan, the maximum benefit in the old regime is:
- Section 24 interest deduction: up to ₹2 lakh/year
- Section 80C principal repayment: up to ₹1.5 lakh (shared with other 80C investments)
- Maximum potential deduction: ₹3.5 lakh/year
In the new regime, neither deduction is available for a self-occupied property. The only benefit in the new regime is the enhanced ₹75,000 standard deduction.
Break-Even Analysis — When Does Old Regime Win?
| Annual Income | Old Regime Advantage | Break-Even Loan Interest | Verdict |
|---|---|---|---|
| ₹10–12 lakh | Marginal (20% bracket) | ~₹3.5L/year interest needed to break even | New regime often better for small loans |
| ₹12–15 lakh | Significant (20–30% bracket) | Home loan interest of ₹2L+ gives ₹40–60K saving | Old regime likely better with typical home loan |
| ₹15–25 lakh | Strong (30% bracket) | ₹2L interest deduction saves ₹60K in tax; 80C saves ₹45K | Old regime almost always better for home loan borrowers |
| Above ₹25 lakh | Strong (30% + surcharge) | ₹3.5L combined deduction saves ₹1L+ in tax | Old regime strongly preferred |
Case Study: Deepak & Kavitha — ₹75L Home Loan in Mumbai
Deepak earns ₹20L/year, Kavitha earns ₹12L/year. They took a joint home loan of ₹75 lakh at 8.75% for 20 years. Annual interest (Year 1): ~₹6.5 lakh. Annual principal: ~₹1.3 lakh. They are co-owners (50-50) and co-borrowers.
Tax treatment (Old Regime, each claiming 50%):
- Deepak: Interest claim ₹2L (max cap) + 80C principal ₹65K = ₹2.65L deduction; Tax saving at 30% = ~₹79,500
- Kavitha: Interest claim ₹2L (max cap) + 80C principal ₹65K = ₹2.65L deduction; Tax saving at 20% = ~₹53,000
- Combined family tax saving: ₹1,32,500/year
New Regime (Deepak + Kavitha, no home loan deduction for self-occupied):
- Both only get ₹75K standard deduction each
- No Section 24 or 80C benefit
- Deepak pays ~₹21,000 more in tax (₹20L income, new regime vs old)
- Kavitha: New regime slightly better if no other deductions (~₹10K saving)
- Net: Old regime saves ₹1,32,500 vs new regime difference is much smaller
Verdict: Old regime saves the couple ~₹1,32,000/year. Stay in old regime.
Let-Out Property — A Different Calculation
The rules change significantly for a let-out (rented) property. Here, home loan interest deduction has no upper cap — you can deduct the full interest paid. And critically, this deduction is available in the new regime too (because it's computing income from house property, not a Section 80 deduction).
How Let-Out Property Works (Both Regimes)
- Gross Rent Received = actual annual rent
- Standard Deduction = 30% of Net Annual Value (NAV) deducted automatically
- Municipal Taxes = deducted if paid by owner
- Home Loan Interest = fully deducted from HP income (no ₹2L cap)
- If result is negative (HP loss), it can be set off against salary — capped at ₹2L/year in both regimes
Under-Construction Property — Pre-EMI Interest
If your home loan was taken before possession, you pay interest during construction (pre-EMI period). This pre-EMI interest:
- Old regime: Deductible in 5 equal instalments starting from the year of possession, within the ₹2L annual cap
- New regime: NOT available — pre-construction interest is lost if you're in the new regime
For those still under construction, this is an additional argument to stay in the old regime — you'd be forfeiting years of pre-EMI interest deduction by switching.
Additional Deduction Under Section 80EEA (If Still Eligible)
Section 80EEA (deduction of ₹1.5 lakh for first-time homebuyers — stamp duty value up to ₹45 lakh, loan sanctioned between April 2019–March 2022) has not been extended. Most borrowers who availed this have already exhausted their eligibility period. However, for those who bought under-construction properties in 2021-22 and are receiving possession now, check if any residual benefit is applicable with your CA.
Case Study: Vikram — Choosing Regime for Under-Construction Flat
Vikram bought a flat for ₹80L in July 2023. He took a ₹65L home loan at 9% p.a. Possession expected March 2027. He's paying pre-EMI interest = ₹65L × 9%/12 = ₹48,750/month = ₹5.85L/year. Total pre-EMI interest (Jul 2023–Mar 2027 = ~44 months) ≈ ₹17.85 lakh.
Starting TY2027-28 (possession year), this ₹17.85L pre-EMI interest becomes deductible in 5 years = ₹3.57L/year. But the ₹2L cap still applies — so max benefit per year = ₹2L. This gives Vikram a guaranteed ₹2L Section 24 deduction for 5 years post-possession.
If Vikram switches to new regime now (TY2026-27): He loses no benefit this year (possession hasn't happened, no deduction available yet). But he risks forming a habit in the new regime before he can claim this deduction from TY2027-28. He should plan to switch back to old regime from TY2027-28 when deductions kick in.
Home Loan — Old vs New Regime: Key Takeaways
- Section 24 interest deduction (up to ₹2L for self-occupied) is ONLY available in old regime
- 80C principal repayment deduction is ONLY available in old regime
- For incomes above ₹15L with a home loan, old regime almost always saves more tax
- Let-out property interest deduction (no cap) is available in BOTH regimes — plan accordingly
- HP loss set-off against salary capped at ₹2L in both regimes; balance carries forward 8 years
- Pre-EMI interest is deductible in 5 years (1/5th each) only in old regime
- Joint home loan: both co-borrowers can claim up to ₹2L interest each — family benefit can be ₹4L
- Review regime choice annually — what's better today may not be optimal next year
